Request InfoQED Technologies Inc.QED Technologies introduces a subaperture stitching interferometer that, it says, increases the utility of a standard Fizeau interferometer by more than five times. SSI, a six-axis computer-controlled workstation, provides automated, high-precision metrology for up to 200-mm-diameter plano, convex and concave parts with clear apertures and high numerical apertures, including hemispherical components. One benefit is automated subtraction of the reference optic's quality. The instrument can be used as a stand-alone metrology system or in combination with the company's Q22 magnetorheological...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2022 IssueFizeau InterferometerThe AccuFiz® Fizeau interferometer from 4D Technology Corp. now features a 9-MP camera for higher slope tolerance through superior spatial resolution.
